斯里兰卡采购需求：钛棒

I am looking to procure various specifications of titanium materials for our upcoming projects. The first category includes multiple sizes of titanium round bars, specifically ranging from 1mm to 14mm in diameter and 3 meters in length, with a quantity of 20 for each size. In addition, I require titanium plates with varying thicknesses from 3mm to 21mm, sized at 4 feet by 8 feet, with 5 pieces for each thickness. Also, I need titanium sheets in dimensions of 1 meter by 1 meter, with thickness options of 0.6mm, 0.8mm, and 1.2mm, requiring 5 pieces of each. Please provide your best pricing and availability for these items.
